Portable device

ABSTRACT

A portable device includes at least one tool driven by a motor and provided in a housing with at least two housing surfaces at relative right angles to each other. One of the housing surfaces is arranged at a right angle relative to the tool and the device includes a plurality of stops fixedly connect and pivotably connected with the housing to be moved out or pivoted out until corresponding stop surfaces are reached. The stop surfaces have different differences with respect to the tool.

BACKGROUND AND SUMMARY OF THE INVENTION

This application claims priority of Switzerland application 2490/98,filed Dec. 15, 1998, the disclosure of which is expressly incorporatedby reference herein.

The invention relates to a portable device consisting of a tool whichcan be drive by a motor, of a housing having two housing surfacesdisposed at a right angle to one another, of these, one housing surfacebeing arranged at, a right angle to the tool, and having one or severalstops.

Portable devices of this type are sold on the market and are thereforeknown. From European Patent Document EP 0666154 A1, a portable, drill isknown and from Swiss Patent Document CH 622981, a portable groovemilling cutter is known which have the advantage that these portablemachines can be stopped on the stops in a precise manner when drillingand groove milling.

Portable devices of the initially mentioned type have the disadvantagethat the stops, such as angle plates, pins and distance plates, areloose parts and that the pivotable stop can be used only for one platethickness or only for one edge spacing with respect to the gang bores.These loose parts must be mounted and adjusted for the machining of thevarious plate thicknesses or various edge spacings with respect to thegang bores. This mounting and adjustment is time consuming andrepresents a source of faults. Often, loose parts must be found beforethe mounting and furthermore these loose parts are easily lost.

It is an object of the invention to provide a portable device which canbe operated in a simple and economical manner for the machining of thevarious plate thicknesses and various edge spacings with respect to thegang bores.

The portable device according to the invention providing thattime-consuming mounting and adjustment of loose parts will no longer benecessary for the machining of the plate thicknesses or various edgespacings with respect to the gang bores which occur most frequently.Furthermore, the source of faults for the correct adjustment isconsiderably reduced, searching for the loose parts is no longerrequired and misplacing of the loose parts is no longer possible. As aresult, the portable device can be operated in a much simpler and moreeconomical manner.

According to an advantageous embodiment of the invention, the stop canbe lowered into the housing because the stop is a pivotable part orbecause a stop body, which can be moved out, is not centrally disposedand has several stop surfaces.

As a further advantageous development of the invention, it is providedthat, as a result of the positioning device, the required stop surfaceof the stop body with several stop surfaces is held on the pin in amanner directed against the workpiece.

As a result of the independent moving-out of the stop pin from the stopbody with several stop surfaces, the stop pin also serves as a centeringdevice for producing a series bore.

Another advantage results from the pivoted-out stop having the threecentering pins so that bores can be made perpendicular to the plateplane for assembly fittings.

Furthermore, because of the construction of the housing surfaces as stopsurfaces, the portable device can be used in a handy manner. Goodaccessibility is ensured in the corners and in furniture pieces.

As a result of the shavings suction device on the housing, the shavingsand the dust can be sucked out of the housing. As a result, thefunctioning of the stops is ensured because the stop surface are free ofshavings and dust.

In a preferred embodiment of the invention the portable device can beused as a hand drilling machine as a result of the drill tool(s).

In another preferred embodiment of the invention the portable device canbe used as a portable groove milling machine as a result of the millingdisk tool.

Other objects, advantages and novel features of the present inventionwill become apparent from the following detailed description of theinvention when considered in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The portable drilling machine illustrated in FIG. 1 includes one or moredrills 1 a operated by a motor, is a housing 2 a which has two housingsurfaces 3 a, 4 a disposed at a right angle relative to one another, ofwhich, the housing surface 3 a is disposed at a right angle relative tothe drill or drills 1 a. The stops 5 a, 6 a, 7 a, 8, 9, 10, 11, 12, 13are fixedly connected with the housing 2 a and can be pivoted out ormoved out or both until they reach one of the stop surfaces 5 a; 6 a; 7a; 3 a; 17 a; 18 a; 19 a or 13′. The stop 7 a, as a pivotable part, ispivoted out of the housing 2 a. By means of the stop surface 7 a′ aplate thickness of 14 mm can be machined. The stop pin 9 is moved outindependently of the stop body 10 with several stop surfaces. The stoppin 9 can be moved out by pressing a projecting pin 21. The stop pin 9is used as a centering device for producing a series bore. By means ofthe stop surface 9′, an edge spacing with respect to gang bores of 28 mmcan be implemented. The stops 8, 10, 11, 12, 13 are lowered in thehousing 2 a. The housing surfaces 3 a, 4 a, 17 a, 18 a, 19 a areconstructed as stop surfaces. No parts project beyond the housingsurfaces 3 a, 4 a, 17 a, 18 a, 19 a. The drilling depth limit 22 with amm scale is also within these stop surfaces. As a result, the portabledevice can be used in a handy manner. A good accessibility in thecorners and in pieces of furniture is ensured. As a result of theshavings suction device 20 a on the housing 2 a, the shavings and thedust can be sucked out of the housing 2 a. As a result, the functioningof the stops 7 a, 9 is ensured because the stop surfaces 7 a′, 9′ arefree of shavings and dust.

The portable drilling machine illustrated in FIG. 2 also shows the stop8, as a pivotable stop, being swivelled out of the housing 2 a. By meansof the stop surface 8′, an edge spacing with respect to the gang boresof 37 mm can be carried out. The stop body 10 with several stop surfaceswhich is not centrally disposed can be moved out by pressing the alsoprojecting pin 21. By means of the stop surface 10′, an edge spacingwith respect to the gang bores of 12 mm can be implemented. Thepositioning device 14 holds the required stop surface 10′ of the stopbody 10 with several stop surfaces on the pin 9 and targeted against thedrill 1 a. The positioning device 14 may, for example, be a threaded pinwith an integrated elastic ball.

The portable drilling machine illustrated in FIG. 3 also shows the stop13 as a pivotable part pivoted out of the housing 2 a. By means of thestop surface 13′ with the three centering pins 16, bores can beimplemented perpendicular to the plate plane for assembly fittings.

The portable groove milling machine illustrated in FIG. 5 consists of amilling disk 1 b which can be driven by a motor, of a housing 2 b whichhas two housing surfaces 3 b, 4 bdisposed at a right angle relative toone another, one housing surface 3 b being arranged at a right anglerelative to the milling disk 1 b. The stops 5 b, 6 b, 7 b are fixedlyconnected with the housing 2 b and can be pivoted out or moved out orboth. The stop 7 b, as a pivotable part, is pivoted out of the housing 2b. By means of the stop surface 7 b′, a plate thickness of 14 mm can bemachined in a centered manner, or the stop surface 7 b′ can be adjustedto a freely selectable angle relative to the millingdisk 1 b. Thehousing surfaces 3 b, 4 b, 17 b, 18 b, 19 b are constructed as stopsurfaces. No parts project beyond the housing surfaces 3 b, 4 b, 17 b,18 b, 19 b. The groove milling depth limit 22 b is also within thesestop surfaces. As a result, the portable device can be used in a handymanner. A good accessibility in the corners and in pieces of furnitureis ensured. As a result of the shavings suction device 20 b on thehousing 2 a, the shavings and the dust can be sucked out of the housing2 a. As a result, the functioning of the stop 7 b is ensured because thestop surface 7 b′ is free of shavings and dust.
